Question

what does it mean: for i=1:length(t) h(i) = hat(t(i)); end

how do I read it? I have difficulties with the interpretation but I know is a hat function.

Answer 1

Explanation:-

• It is for loop execution in MATLAB
• Here i is a variable for index of the vector t
• Another vector h is declared
• In MATLAB index start from 1
• So loop through 1 to length of vector t
• Take each element of t using t(i)
• Ans pass as argument for your 'hat' function
• Your hat function return a value which is assign to the vector h's corresponding index

        %Loop through from first index to end of the vector t
for i=1:length(t)
    %Assign vector h's corresponding index value as the hat function return value
    %Pass t's corresponding index value as argument to hat function
    h(i) = hat(t(i));
%End of for loop
end

Note:-

I assume you implemented your hat function separately.
